Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-6 The present invention provides a technical solution: a deep embossing die-cutting equipment suitable for thick plates, including a frame 1, and a feeding mechanism 2, a positioning mechanism 3, an embossing die-cutting mechanism 4, a flattening mechanism 5 and a receiving mechanism 6 arranged sequentially on the frame 1 along the plate conveying direction.

[0017] The feeding mechanism 2 includes a feeding conveyor belt 21 and a guide assembly 22. The guide assembly 22 is symmetrically fixed on both sides of the feeding conveyor belt 21 and maintains a gap of 0.5-1mm with the side of the plate. The feeding conveyor belt 21 is driven by a feeding motor, and the feeding motor is electrically connected to the controller.

[0018] The guide assembly 22 includes a fixed support 221, a locking bolt 222, a sliding rod 223, and a guide plate 224. The fixed support 221 is fixed to the side of the feeding conveyor belt 21.

[0019] The guide plate 224 is made of polytetrafluoroethylene to increase wear resistance. It is an angle plate of 150°-175° with a curved transition at the corner. The guide plate 224 is always located above the feeding conveyor belt 21 and never comes into contact with it, which facilitates the positioning and conveying of thick plates.

[0020] The positioning mechanism 3 includes a support frame 31, a cylinder 32, a guide rod 33, a movable frame 34, and a positioning conveyor belt 35. The support frame 31 is fixed to the machine frame 1.

The cylinder 32 is electrically connected to the controller. The guide rod 33 is also fixed on the upper side of the movable frame 34, passing through the support frame 31 and slidably connected to it. This mechanism enables the thick plate material emerging from the guide assembly 22 to be clamped and conveyed by the feeding conveyor belt 21, ensuring that the position of the thick plate material remains unchanged during the feeding process, effectively avoiding die-cutting deviation. At the same time, while stabilizing the feeding, it also facilitates the forward pushing of the die-cut thick plate material, which is already processed, for easy unloading after die-cutting.

[0021] The station sensor is fixed on the discharge side of the positioning mechanism 3 and electrically connected to the controller. It is used to detect the position of the board and trigger the feeding motor to stop.

The top of the lower die base is provided with an embossing die and a die-cutting groove to ensure that embossing and die-cutting are completed simultaneously.

[0023] The flattening mechanism 5 includes a second support frame 51, a second cylinder 52, a second guide rod 53, a second movable frame 54, a lower pressure roller 55, and a support roller 56. The second support frame 51 is fixed to the machine frame 1. The second movable frame 54 is located inside the second support frame 51, and the lower pressure roller 55 is installed inside the second movable frame 54. The support roller 56 is rotatably connected to the bottom inner side of the second support frame 51 and is driven by a motor. The support roller 56 is located directly below the lower pressure roller 55. The second cylinder 52 is fixed to the top of the second support frame 51. The second movable frame 54 is fixedly connected to the end of the piston rod of the second cylinder 52. The second guide rod 53 is also fixed to the upper side of the second movable frame 54. The guide rod 53 passes through the second support frame 51 and is slidably connected to it. The height of the lower pressure roller 55 can be adjusted by a controller to adapt to the flattening requirements of plates of different thicknesses.

[0024] The surfaces of the pressure roller 55 and the support roller 56 are both covered with an elastic rubber layer to ensure safe contact with the thick plate.

[0025] The receiving mechanism 6 includes a receiving conveyor belt 61, a material blocking assembly 62, and a buffer plate 63. The material blocking assembly 62 is symmetrically arranged on both sides of the receiving conveyor belt 61, and the buffer plate 63 is fixed at the end of the receiving conveyor belt 61.

[0026] The material blocking assembly 62 includes a second fixed support 621, a second locking bolt 622, a second sliding rod 623, and a material blocking plate 624. The second fixed support 621 is fixed to the side of the receiving conveyor belt 61. The second sliding rod 623 is slidably connected through the upper end of the second fixed support 621. The material blocking plate 624 is fixed to the end of the second sliding rod 623. The second locking bolt 622 is threadedly connected to the upper end of the second fixed support 621. The inner end of the second locking bolt 622 abuts against the second sliding rod 623. The working position of the material blocking plate 624 can be adjusted to facilitate the use of thick plates of different sizes.

[0027] The baffle plate 624 is a straight plate made of polytetrafluoroethylene (PTFE) to ensure wear resistance. Its curved ends ensure proper movement between the baffle plates 624. The baffle plate 624 remains above the receiving conveyor belt 61 and never contacts it, preventing the material from shifting during the receiving process.

[0028] The feeding mechanism 2, the embossing and die-cutting mechanism 4, the flattening mechanism 5 and the receiving mechanism 6 are connected by a transition plate 7, which allows the thick plate to smoothly transition from one conveying position to the next, avoiding conveying jams or deviation of the thick plate's posture.

[0029] Specifically, when using this deep embossing die-cutting equipment suitable for thick plates, the controller first starts the receiving conveyor belt 61 and the feeding conveyor belt 21, places the thick plate on the feeding conveyor belt 21, and adjusts the position of the guide plate 224 on the guide assembly 22 according to the size of the thick plate and the conveying position. The guide plate 224 of the guide assembly 22 guides the plate to move along the conveying direction to prevent conveying deviation. The sheet material is clamped from above and below by the positioning conveyor belt 35 and the feeding conveyor belt 21, so that the sheet material is stably fed into the embossing and die-cutting mechanism 4. When the sheet material triggers the station sensor, the sensor sends a signal to the controller, and the controller immediately stops the feeding motor and the feeding conveyor belt 21. Once the sheet metal is fully inserted into the lower mold base, the controller drives the piston rod of the dual hydraulic cylinder to extend, causing the upper mold base to move downward along the guide post. The embossing punch of the detachable mold cooperates with the embossing die of the lower mold base to complete deep embossing, while the die-cutting blade cooperates with the die-cutting groove to complete die-cutting. Subsequently, the piston rod of the dual hydraulic cylinder retracts, and the upper mold base resets. The die-cut sheet is pushed out by the sheet conveyed from the rear to the front and conveyed to the flattening mechanism 5. The controller adjusts the cylinder 52 to make the lower pressure roller 55 press down, which cooperates with the support roller 56 to flatten the sheet. The flattened sheet enters the receiving conveyor belt 61, and after being guided by the baffle plate 624 of the baffle assembly 62, it is smoothly conveyed to the buffer tray 63 to complete a single processing.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
